IDAYBOOK.

Application filed July 16, 1927, Serial No.

The commonly-used day-books are not very practical as it is necessary to run over all the pages every day to ascertain for which papers an appointment has been made. The turning over of the leaves requires much time, specially when there are many documents to examine.

This invention relates to a day-book which is free from this inconvenience, saves time and makes it impossible to overlook any appointment.

According to the invention the file or book has a noting-arrangement, comprising squares for marks which indicate at which day a case comes on, a letter has to be answered or a payment has to be made.

An embodiment of the invention is shown, by way of example, in the accompanying drawing, in which Fig. 1 shows an improved day-book, the top sheet being partly broken away.

Figs. 2 and 3 show on larger scale a portion of the noting-arrangement in section and front elevation respectively.

A file or book a has at the right-hand end an alphabetical index I), composed of flaps projecting from the filing sheets.

On the front cover of the file a noting device is fixed or removably attached on the This noting-device consists of two sheets 0, d of suitable material, preferably cardboard, lying the one on the other and held together. The lower sheet 0 has no perforations. The upper sheet (Z is subdivided by horizontal and vertical lines into small squares, the rows of squares in the one direction being designed for the days of the month and those in the other direction being designed for the letters f of the alphabet. Several rows of letters of the alphabet are arranged in order to facilitate the finding of adocument.

It is evident that the rows of squares for the days might be vertical and those of the letters of the alphabet horizontal or inversely.

Each square on the front sheet 0 is arranged to hold a device for marking the day, this device being adapted to be removed and placed into any other day square.

With this object in view each square has a circular hole 9, designed to receive the neck 2' of a button i said neck fitting tightly into the hole. On the end of the neck 1' of the buttonh a thin elastic tonguek is fixed.

206,212, and in Germany October 22, 1926.

The button 72. is painted in a conspicuous colour, for instance red.

The several sheets of the file or book have each a tongue Z under which the documents to be preserved are held.

The papers or documents to be used at certain dates are filed in the book or file under the corresponding letter of the alphabet. A button has to be inserted into the hole of that square on the top sheet which corresponds to the date and to the letter under which a document has been filed. The elastic tongue 70 of the button is securely held between the sheets 0 and d so that the button is securely fixed and cannot drop out even when the file is being handled. The top-sheet (Z in Fig. 1 shows a mark for the 2nd of the month and for a document filed under the letter V, for the 3rd of the month and a document filed under the letter C, for

' the 6th of the month and for the document vment filed under the letter D.

Each day the day-file has to be examined and the documents marked under the corresponding date are easily found so that it is almost impossible to forget a case due on a certain date.

The marking-device might consist only of one sheet, the cover of the file serving as lower sheet.

Instead of buttons fiat slides might be used to be inserted into a slit in the square, said slides being painted on the opposite sides thereof with different colours.

The marking device might be used without any signs to be inserted, in which case a cross with a blue pencil has to be made in the corresponding square.

, I claim 1. A day-book, comprising in combination with a file having index-sheets, a marking device subdivided into squares designated by figures and letters, and markers adapted to be fixed on the squares which correspond to certain dates and to certain letters filed under the corresponding letter in the book or file.

2. A day-book, comprising in combination with a file having alphabetical indexsheets, a marking-device consisting of two sheets of suitable material lying the one on the other, the top sheet being subdivided by hor- 5 spond to certain dates and to'certain letters" filed under the corresponding letter in the" 3 In a day-book as specified in claim 2 the marks consisting each of a button and of a neck which is adapted to fit into the holes of the squares and of a thin spring blade fixed to the end of the neck and designed to engage between the two sheets.

In testimony whereof I affix my signature.

HANS HAMMER.
